I was shooting my Omega. I was using 90gr of T7 FFg. Then I went up from there in 5 grain incraments and stopped at 100gr. I am not sure how to explain the bullet shape. It has a slightly tapered nose that turns flat nose with three ribs going down the side. I bought the cast from Lee Realoading and its the 250gr. .45 cal. bullet mold. Thanks for the tips. I believe I will start at a lighter load like yall mentioned and work my way up from there. Thanks again.
